Check to see if you are getting fuel delivered. Check to see if you have spark. Check your compression. If you have all of these, the only other thing left is timing, which is unlikely if you have compression. By the way, did the relearn turn your Security light off? Dick

Replying to: lovemygrandam (Apr 18, 2009 7:08 am) Problems started several months ago . I took the car thru a car wash - the next day , no start . Did the reset and got it going again. Started having to do the reset thing again every few days until i found this forum . I checked the BCM - all looked good . Tried the resistor fix - didn't work . Finally i cut the yellow wire and things were fine (although the security light stayed on) . Several weeks ago I took the car thru a car wash again - next day we lost our daytime running lights (i think at that time the service vehicle light had come on too). Days later the light was off and the running lights were back on . all has been good since then , until today . We've been getting a lot of rain over the last few days . My wife started the car this morning but the clock had reset .She reset the clock went out to eat .When she went to start the car ( raining all day) the clock had rdefaulted back to12:00 again . She went visiting and when she was done tried starting the car , but completely dead . The car is at her friends now . My game plan , for now is to wait until tomorrow - turn on my toggle switch - do the reset and hopefully it'll start . Anyway it's not looking like a Passlock issue now , from what i've read here it should be the BCM . (moisture issue ?) Thoughts anyone ? If you think it's my BCM - what is the best approach ? Is the BCM junk now or is there a way to seal it or something ? Is there a test for this ? Should the dealer do the replacing ? etc etc. Thanks in advance .

HI I have a 2001 Pont Grand AM SE1 and have done everthing I know to get the lockout off of my radio.. I have tried to unhook the batt for an hour and then pushing buttons 2 and 3 for about 10 sec.. nothing.. then I tried it again pushing buttons 1 and 4 thats what the owners manual says.. Then I just did the same thing but just let the ingnition stay on for an hour.. and did the same thing as I did when I unhooked the Batt. Welp.. I called GM and talked to about three people and all said... in so many words......your problem not ours.......what a great idea GM had running everthing thru the radio wires.......lol If anyone knows how I can bypass this or another way of fixing it rather than taking it to a dealer and them putting it on a machine to get some codes.. let me know Email me at RMHCowboy  aol.com Thank you................

This may include keyless fobs from your other GM cars. 2. Go to a chevy dealer instead of a Pontiac dealer. They generally charge less to attach and run the diagnostic instrument. My chevy dealer charges $25.00, and my Pontiac dealer charges $40.00. That's a difference of 6 tall latte's at my local coffee shop. Dick. |

Replying to: markjr54 (Apr 16, 2009 11:27 am) You have the PASSLOCK also known as MRD to locksmiths as anti-theft system. The security light is telling you there is a malfunction in the system. The use of different keys means nothing becuse the security is built into the lock/ housing portion. The ignition key for this vehicle does not have a chip in it and a duplicate key can be made at a hardware store. The way this system works is the vehicle's computer has to see the rotation of the ignition lock and the computer is not seeing this in your instance. This system has a magnetic field in the ignition housing as it relates to the lock. If the lock is forced from the housing the field is broken and the engine will not start. What I have seen to be a common problem over time is that ignition lock lubricatant sprayed on the outside of the lock and into the housing eventually making it so the vehicle's computer can not see you rotating the ignition to ON. The correction would be; have a locksmith remove the ignition lock and clean the body of the lock and inside the housing. Reinstall and that seems to fix the problem in many cases. If this is not the problem, you will need to take it into the dealer to scan for codes. Good Luck!

Replying to: originalmrmike (Apr 26, 2009 2:31 pm) It's funny that in these later posts, there are many instances of the Security light being on SOLID, which indicates that the Security system has malfunctioned, and is being bypassed, and even though the owner goes through the 10 minute relearn cycle, the Security light does not get reset, but the car does run. This seems to indicate that as time goes by, the BCM's are failing, but there is no conclusive evidence that this is what is happening. Good luck to all. Dick |

I also followed you procedures however my security light stayed on and the BCM never reset. I took the BCM out, looked inside and unfortunately the computer board has corrosion and is toast. Since I have already done the bypass, can I buy a used BCM at a salvage yard, install it and have that actually work? Considerably less cost from the salvage yard. They are quoting me about $75.00.
